But basically here is how the form works. 

 
the html file sets the fields and the form namethen the php file you have   

$form = new Form('formname');  

then in the php file you set the fields to what you want 

example:  you can call it whatever you want, such as  $MyFormData         

         $MyFormData = new TextField('fieldname');

         $MyFormData->setLabel($language->text('pluginname', 'lang key here'));

         $MyFormData->setRequired(); 

         $MyFormData->addAttribute('size','10');

         $MyFormData->addAttribute('maxlength','30');

         $form->addElement($MyFormData); 

then once you have all your fields assigned then you just add the form
$this->addForm($form);  

Then when you submit the form it looks for the request that is a post request which is secure (there is post and get)  and you also run it through the validator

  if( OW::getRequest()->isPost() )         

  {           

      if ( $form->isValid($_POST) )             

       {

    then to get the values of the form  
    $values = $form->getValues();

     
example of one value would be 

     $vidtitle = $values['vidtitle'];  whatever you called your fieldname

if you want to view the whole array of the form you can do 

echo "<pre>";

print_r($values);

exit;

does that help?

        OW::getEventManager()->bind(PostService::EVENT_AFTER_ADD, array($this, "onAfterPostAdd"));

        OW::getEventManager()->bind(PostService::EVENT_AFTER_EDIT, array($this, "onAfterPostEdit"));

also there is a save event in the blogs controllers save.php file 

                OW::getEventManager()->trigger(new OW_Event(PostService::EVENT_AFTER_ADD, array(

so you might be able to work that same logic using the postservice into your plugin or find same event in forum
